For now you might wish to consider using a Toggle button plugin to control the opening and closing of the Map?
If using a toggle button to show a large section of google map the control bar will be covered by the map.
So what, you cannot manipulate the tour - using the control bar - while the map is covering it?
You could alternatively use a vertically orientated control bar?
After clicking on a point on the map you have to push back the map manually to get the pano into view again. That is not so fine.
Thank you for your efforts.
If you use a Toggle button then clicking the button a second time - when the Map is open - will close the map. that's why it's called a Toggle button.
1. Use a Planar image in the tour as the Map.
2. Use a graphic map as a Floorplan image.
